iPhone Keeps Randomly Crashing, Rebooting, and Showing Extreme Battery Drain

Yep, I knew it WAS strange as...well you know. Shared it anyway. 😳

It’s done this to my iPhone 12 mini 3 times now!

...and when I reboot a second time, the battery charge is magically at or near 100% again.

what iOS is your iPhone 12 MaxPro running?

I'm uaing iphone 12 and it still keep crashing.

mistterius,

I can promise you Apple is not doing this on purpose to cause anyone any distress. That is contradictory to the way business’ operate.

Ok, so you are running iOS beta 14.0.1, you should update to the non-beta iOS 14.1 or the current beta iOS 14.2 GM.

As far as your battery draining so rapidly turn off “background app refresh”, this is one of the recommended fixes for beta iOS 14.0.1.

Go to this link, they talk about your issue and how to work around this issue.

I highly recommend you update your iOS to the current, either beta iOS 14.2 GM or non-beta iOS 14.1. This might fix your battery issue. Good luck!

Good advice, for perhaps someone who has a bunch of apps open.

Even better advice for someone who routinely “closes” apps. The apps in the quick-launch screen are not running; they are suspended. Other than the 3 or 4 most recent ones, the aren’t even in memory. Deleting apps from that page actually increases battery drain and slows down your phone. See—>Do not close "background" apps | Communities

I understand your frustration but in your provided screenshot you can clearly see that your battery is in need of a service.

Whether this new update is actually responsible for these issues, I don’t know. Not all devices are affected, only some.

What I do know however is that a phone with poor battery health is going to suffer in terms of performance, even if you hadn’t installed iOS 14 you would definitely have had problems sometime in the future.

My advice would be to get the battery replaced anyway, and keep an eye out for any new updates that’ll patch the battery drain issue your iPhone may be suffering from.

*You can mail your device to Apple if there’s no store open nearby.

Battery capacity isn’t necessarily relevant. If the battery was installed improperly or the wrong type of battery was involved, that could trigger the “service” indicator also.

I know it’s difficult with stores being closed to get serviced.

Have you tried updating the phone again? You mentioned iOS 14.0.1 earlier which has since been replaced by 14.1. According to Apple the latter contains numerous bug fixes and improvements which could help.

missterius,

Definitely let me know how it goes. I will await the results.

Try to remember that the iPhone is NOT a phone but a portable and extremely powerful hand held S.M.A.R.T. computer. It is an extremely complicated device that does everything we need it to, we want it to, and we never thought about it ever doing. We could be dragging around a laptop, a phone, game console, books, boom box, cd’s, calendars, etc... OR an iPhone. Yes, I had a difficult time adapting to the iPhone, my first Apple product ever, because it had little annoying bugs I felt offended that Apple expected me to put up with. But I ended up absolutely addicted to every one of my iPhones and don’t know what I would do with out it. I absolutely trust and respect Apple and it’s devices. It is everything I need in one tiny little amazing hand held device. And in my opinion, Apple’s iPhones are un-rivaled. So yes, you have the right to be frustrated but remember what it actually does for us and as I had to do... we have to stop expecting perfection from a fluid , constantly growing, always increasing in amazing functions, and abilities in an extremely powerful device. Let’s give Apple the appreciation and break it truly deserves. Plus you have to respect a company that created a forum where it’s users can vent about IT and still provide the help to the frustrated, from a large community to address issues you are having with THE company’s product. Hang in there... powerful technology deserves our participation in making it better. We are here to help you do just that. But yes, you have every right to be upset, angry, irritated, frustrated... but not for too long because you need help in figuring out your phones particular personality quirks. We were here to help. 😎 Hang in there!

Apple’s software Quality Assurance has definitely gone downhill recently. Even though I’ve had no battery issues, iOS 13 and 14 have both been riddled with bugs from the start.

This is why I generally wait till minor updates are released before moving up to a new software version just to escape the worst of it. Things should improve with time.

Even if you are tired of hearing it, your battery is bad. Those are the symptoms of a failing battery with high internal resistance. And I have read the whole thread, several times over, and that doesn’t change the fact that your battery is bad. You can use the Contact Support link at the top of this page, where a technician can run a remote diagnostic, and then she can tell you that your battery is bad rather than other users telling you that your battery is bad, but that doesn’t change the fact that your battery is bad.
